Dave over the years that I have been selling my wares in different markets one thing above all was very clear. What you think should be a good seller and what the potential wants of the customers can be and almost always are different. You can somewhat minimise this by having a wide selection of different things. Team plaques, Championship plaques and signs, awards and potential trophies that can be ordered, that kind of thing. Glad you did well at the farmers market.
